HIP 91258 and Its Close-Orbiting Planet

HIP 91258 is a G-type main-sequence star 150 light-years away, with a reported age of 2.4 billion years, a mass of 0.95 solar masses, a radius of 1 solar radii, and a temperature of 5520 K. The star's reported mass estimate is smaller than the Sun's, and its reported temperature is cooler than the Sun's. One known planet orbits this host.

That planet, HIP 91258 b, was discovered in 2013 by the radial velocity method, which measures the wobble a planet's gravity induces in its star's motion. Its minimum mass is 346 Earth masses, larger than Earth's, and it completes an orbit in 5.05 days. Because this is a minimum mass, it is a lower bound on the planet's true mass rather than an ordinary mass estimate.
